Minnesota Vikings coach Leslie Frazier is spending this July 4th week in the Persian Gulf, visiting U.S. troops as part of a USO tour. Former NFL coaches Bill Cowher and Eric Mangini, now television analysts, are also among the group.

From an Associated Press story:

"Frazier said when he got back, he'd remind his daughter that whenever she sees servicemen and women, to thank them. And he won't have much patience if his players gripe about the heat during training camp.

'It just puts in perspective that there's nothing you should ever complain about,' he said."

We're in the midst of the only downtime that NFL coaches have during the year -- the time between the end of offseason workouts and the start of training camp. There are lots of ways to spend that time, but I would imagine Frazier couldn't find anything more rewarding.
